I saw this: Extra: Last beacon: 82044ms agoI think this is unusually high, but might be just that the access point is set up that way.
You didn't receive a beacon frame for 82 seconds. That means that sometimes you might have to wait that much in order to detect the AP on the machine.
Increasing the signal might help, but your signal level isn't that low. You can have >11M speed with this level.
